PTFE Coating
High-Performance Fluoropolymer Coatings by Petrotube
What is PTFE Coating?
Polytetrafluoroethylene (PTFE) is a non-stick fluoropolymer coating known for its exceptional heat resistance, low friction, and superior chemical resistance. It offers a high operating temperature compared to other fluoroplastics, making it an ideal choice for industrial applications. PTFE coatings also provide medium to fair abrasion resistance, making them suitable for harsh environments.
Where is PTFE Used?
PTFE coatings are extensively applied in Oil & Gas, Marine, and Offshore industries to protect fasteners from extreme environmental conditions.
PTFE-coated fasteners deliver :
✔ Superior Corrosion Resistance – Exceptional performance in salt spray and offshore environments.
✔ High-Temperature Resistance – Withstands up to 600°F, outperforming other fluoropolymer coatings.
✔ Excellent Release Properties – Prevents material build-up, reducing maintenance requirements.
✔ Durability in Aggressive Conditions – PTFE, commonly known as Teflon, Xylan, or Fluoropolymer coatings, is widely used in onshore and offshore applications.
PTFE Coating Process at Petrotube :
Our advanced PTFE coating process ensures high durability and performance:
1️⃣ Surface Preparation – Components are heated to remove contaminants such as oil, dirt, and other residues.
2️⃣ Abrasive Sandblasting – Enhances adhesion by roughening the metal surface.
3️⃣ Primer Application – A zinc base coat (20-micron thickness) is applied to enhance adhesion and corrosion resistance.
4️⃣ PTFE Top Coat Application – The final PTFE layer is applied, providing a smooth, durable finish.
5️⃣ Color Options – Available in black, blue, green, red, white, yellow, orange, and purple to suit diverse industrial requirements.
Advantages of PTFE Coating :
✔ Withstands Extreme Temperatures – Operates in high-heat environments up to 600°F.
✔ Low Friction & Non-Stick Properties – Ideal for reducing wear and tear in fasteners.
✔ Corrosion Resistance – Excellent performance in marine, offshore, and industrial environments.
✔ Chemical Resistance – Protects against aggressive chemicals, acids, and solvents.
✔ Ease of Assembly & Removal – Ensures smooth operations without material buildup.
